Description

Technical Field

[0001] This application relates to the field of keyboard key cover assembly fixture technology, and more particularly to a keyboard key cover assembly fixture. Background Technology

[0002] Keyboard keycap assembly fixtures are primarily used to facilitate the accurate and efficient installation of keyboard keycaps. However, current keycap assembly fixtures typically require operators to manually calibrate the keycap position and tilt the keycap to ensure proper alignment and mating between the keycap and the keycap. This tilting of the keycap allows the snap-fit ​​groove on one side of the keycap to engage with the corresponding snap-fit ​​piece on the keycap. This cumbersome assembly structure leads to a high rate of scrap, resulting in low overall keycap assembly efficiency.

[0003] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a keyboard keycap assembly fixture, which aims to improve the assembly efficiency of keyboard keycaps and reduce the scrap rate of keycaps.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: a keyboard key cover assembly fixture, comprising:

[0006] The clamping assembly is used to clamp and fix the injection molded keycap part. Several keycaps are arranged and fixed on the injection molded keycap part. The clamping assembly has through holes at the positions corresponding to the keycaps. The through holes extend along a first direction and the size of the through holes is larger than the size of the keycaps.

[0007] The keycap lower mold is set below the fixture assembly. A positioning and fixing boss is provided on the keycap lower mold at the position corresponding to the through hole. The positioning and fixing boss extends along the extension direction of the through hole and is used to insert into the through hole, thereby detaching the keycap from the keycap injection molded part.

[0008] And a keycap upper mold, which is set on the clamping assembly, and a first receiving groove is formed between the keycap upper mold and the clamping assembly. The first receiving groove is used to fix the keyboard key core.

[0009] One side of the positioning and fixing boss is provided with at least one keycap pin, which is used to lift the keycap that has been detached from the keycap injection molding part, so that it is assembled onto the key core at a preset tilt angle.

[0010] In one possible implementation, the fixture assembly includes:

[0011] A keycap spring plate is provided on the lower mold of the keycap, and a second receiving groove for fixing the injection molded keycap part is provided on the keycap spring plate.

[0012] And a clamping plate, which is set on the keycap spring plate and is used to abut and fix the keycap injection molded part;

[0013] The keycap spring plate and the fixture plate are respectively provided with a number of first limiting openings and second limiting openings, and the first limiting openings and second limiting openings are connected to form a through hole.

[0014] In one possible implementation, the upper mold of the keycap, the lower mold of the keycap, the keycap spring plate, and the fixture plate are all metal structures.

[0015] In one possible implementation, a plurality of key core ejectors are provided on the end of the keycap upper mold facing the clamping assembly, and the key core ejectors are used to abut against the keyboard key cores.

[0016] In one possible implementation, both the key core pin and the key cap pin are elastic, retractable pins.

[0017] In one possible implementation, the button cap pin is located on one side of the positioning and fixing boss, and the button cap pin extends along a first direction.

[0018] In one possible implementation, a keycap ejector pin and a spiral elastic element are sequentially inserted through the through hole. A limit cap is provided on one end of the keycap lower mold away from the positioning and fixing boss. The limit cap is used to block the through hole so that the two ends of the spiral elastic element abut against the limit cap and the positioning and fixing boss respectively, so that the keycap ejector pin can elastically extend and retract along the first direction.

[0019] In one possible implementation, a keycap bakelite base is provided below the lower mold of the keycap, which is used to fix the upper mold of the keycap.

[0020] In one possible implementation, both the through hole and the positioning and fixing boss extend along a first direction, which is the thickness direction of the keycap lower mold.

[0021] Compared with existing technologies, this application provides a keyboard keycap assembly fixture. In use, the keyboard key core and keycap injection-molded parts are first placed in the second and first receiving grooves, respectively. Then, the upper mold of the keycap is pressed down, causing the keycap to detach from the keycap injection-molded part and assemble onto the key core. During assembly, the keycap is lifted from the injection-molded part by a keycap ejector pin, maintaining it at a preset tilt angle close to the key core, allowing the snap-fit ​​mechanism on the key core to more easily engage with the snap-fit ​​groove of the keycap. This improves the assembly efficiency of keyboard keycaps and reduces the scrap rate of keycaps. Attached Figure Description

[0032] 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.

[0033] This utility model provides, for example Figure 1 , Figure 2 and Figure 3As shown, a keyboard keycap assembly fixture is used to detach keycaps from the keyboard keycap injection molded part and assemble the keycaps onto the keyboard key core. The main structure includes: a fixture assembly 1, a lower keycap pressing mold 2, and an upper keycap pressing mold 3. The fixture assembly 1 is used to clamp and fix the keycap injection molded part. It should be noted that several keycaps 4 are arranged and fixed on the keycap injection molded part, and are integrally formed. Therefore, the keycaps 4 need to be detached from the keycap injection molded part before assembly. A through hole 13 is provided on the fixture assembly 1 at the position corresponding to the keycap 4. The through hole 13 extends along a first direction and its size is larger than that of the keycap 4. The keycap pressing lower mold 2 is set below the fixture assembly 1. A positioning and fixing boss 21 is provided on the keycap pressing lower mold 2 at the position corresponding to the through hole 13. The positioning and fixing boss 21 extends along the extension direction of the through hole 13 and is used to insert into the through hole 13, thereby detaching the keycap 4 from the keycap 4 injection molded part. The keycap pressing upper mold 3 is set on the fixture assembly 1. A first receiving groove 31 is formed between the keycap pressing upper mold 3 and the fixture assembly 1. The first receiving groove 31 is used to fix the keyboard key core and matches the keyboard key core. At least one keycap ejector pin 212 is provided on one side of the positioning and fixing boss 21. The keycap ejector pin 212 is used to lift the keycap 4 detached from the keycap 4 injection molded part and assemble it onto the key core at a preset tilt angle. Specifically, during the pressing process between the clamping assembly 1 and the keycap, the positioning and fixing boss 21 is inserted into the through hole 13, thereby ejecting the keycap 4 from the keycap injection molded part. The ejected keycap 4 continues to be pushed up, and with the support of the keycap ejector pin 212, one side of the keycap 4 is pushed up by the keycap ejector pin 212, keeping the keycap 4 at a preset tilt angle close to the keyboard key core. Until the keycap 4's snap-fit ​​groove engages with the key core's snap-fit ​​member, the keycap 4 is finally assembled onto the key core.

[0034] It should be noted that current keyboard keycap assembly fixtures typically require operators to manually calibrate the keycap position and tilt the keycap to ensure proper alignment and fit between the keycap and the keycap. This allows the locking slot on one side of the keycap to engage with the corresponding locking piece on the keycap first. This fixture assembly structure is cumbersome, resulting in a high rate of scrap and consequently, low overall keycap assembly efficiency.

[0035] In use, the keyboard key core and keycap 4 injection-molded parts are first placed in the second receiving groove 111 and the first receiving groove 31, respectively. Then, the upper mold 3 of the keycap is pressed down, causing the keycap 4 to detach from the injection-molded part and be assembled onto the key core. During assembly, the keycap 4 is lifted from the injection-molded part by the keycap ejector pin 212, keeping it at a preset tilt angle close to the key core, so that the snap-fit ​​parts on the key core can more easily snap into the snap-fit ​​groove of the keycap 4. This improves the assembly efficiency of the keyboard keycap 4 and reduces the scrap rate of the keycaps.

[0036] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixture assembly 1 includes a keycap spring plate 11 and a fixture plate 12. Specifically, the keycap spring plate 11 and the fixture plate 12 are stacked. The keycap spring plate 11 is disposed on the lower mold 2 of the keycap, and a second receiving groove 111 for fixing the injection-molded keycap 4 is provided on the keycap spring plate 11. The second receiving groove 111 matches the injection-molded keycap 4. The fixture plate 12 is disposed on the keycap spring plate 11 and is used to abut against and fix the injection-molded keycap 4. The keycap spring plate 11 and the fixture plate 12 are respectively provided with a plurality of first limiting openings 131 and second limiting openings 132, which are connected to form a through hole 13. Specifically, the first limiting openings 131 and the second limiting openings 132 both extend in the same opposite direction. In some embodiments, the two are the same size. When the keycap spring plate 11 and the clamp plate 12 are combined, the first limiting opening 131 and the second limiting opening 132 are combined to form a through hole 13, wherein the keycap 4 is located between the first limiting opening 131 and the second limiting opening 132.

[0037] Furthermore, the upper mold 3, lower mold 2, spring plate 11, and fixture plate 12 of the keycap are all metal structures. It is understandable that the metal upper mold 3, lower mold 2, spring plate 11, and fixture plate 12 have greater structural strength and can withstand the high frequency of use during assembly line production.

[0038] Furthermore, such as Figure 3 As shown, the upper mold 3 for pressing the keycaps has several keycap ejector pins 32 at one end facing the clamping assembly 1. These pins 32 are used to abut against the keyboard keycaps. It is understood that during the assembly of the keycaps 4 to the keycaps, the force applied to the keycaps 4 may cause the keycaps to shift backward due to the limited structural strength of the keycaps. Therefore, in this embodiment, several keycap ejector pins 32 are provided at one end of the upper mold 3 for pressing the keycaps, facing the clamping assembly 1. These pins 32 support the keyboard keycaps and prevent them from shifting backward during the engagement of the keycaps 4.

[0039] Furthermore, such as Figure 3 and Figure 5 As shown, both the key core ejector pin 32 and the key cap ejector pin 212 are elastic and retractable ejector pins. It is understandable that the elastic and retractable key core ejector pin 32 and key cap ejector pin 212 provide a certain buffer distance for both the key core and the key cap 4, preventing damage to the key cap 4 and key core during the clamping and assembly process.

[0040] Furthermore, such as Figure 4 As shown, the button cap ejector pin 212 is disposed on one side of the positioning and fixing boss 21, and the button cap ejector pin 212 extends along a first direction. The first direction is the extension direction of the positioning and fixing boss 21, and is also the direction in which each clamp is pressed or separated.

[0041] Furthermore, such as Figure 5 As shown, the positioning and fixing boss 21 has a mounting hole 211. A keycap ejector pin 212 and a spiral elastic element 213 are sequentially inserted through the mounting hole 211. A limit cover is provided on one end of the keycap lower mold 2 away from the positioning and fixing boss 21. The limit cover is used to block the through hole 21413 so that the two ends of the spiral elastic element 213 abut against the limit cover and the positioning and fixing boss 21 respectively, so that the keycap ejector pin 212 can elastically extend and retract in the first direction.

[0042] Furthermore, such as Figure 2 , Figure 3 As shown, a keycap bakelite base 5 is also provided below the keycap lower mold 2, which is used to fix the keycap upper mold 3.

[0043] Furthermore, such as Figure 2 , Figure 3 As shown, both the through hole 13 and the positioning and fixing boss 21 extend along the first direction, which is the thickness direction of the keycap lower mold 2.

[0044] In summary, this application provides a keyboard keycap assembly fixture. In use, the keyboard key core and keycap 4 injection-molded parts are first placed in the second receiving groove 111 and the first receiving groove 31, respectively. Then, the upper mold 3 of the keycap is pressed down, causing the keycap 4 to detach from the injection-molded part and be assembled onto the key core. During assembly, the keycap 4 is lifted from the injection-molded part by the keycap ejector pin 212, maintaining it at a preset tilt angle close to the key core, so that the snap-fit ​​parts on the key core can more easily snap into the snap-fit ​​groove of the keycap 4. This improves the assembly efficiency of the keyboard keycap 4 and reduces the keycap scrap rate.

[0045] 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.
