Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of keycap laser engraving fixture fixing device, specifically relating to a flip-up keycap laser engraving fixture fixing device. Background Technology
[0002] Some existing keyboard keycaps have laser-engraved patterns on their top and sides. These keycaps typically require a two-step processing method. First, a keycap fixture is fixed to a horizontal mounting plate to laser-engrave the top pattern on the keycap. Then, the fixture is fixed to a tilted mounting plate to laser-engrave the sides, completing the keycap processing. This process requires two mounting plates (horizontal and tilted) to hold the keycap and process both the top and sides, increasing the equipment's footprint. Furthermore, after laser-engraving one side of the keycap, the fixture needs to be removed from one mounting plate and then fixed to the other, making the operation complex and reducing processing efficiency. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flip-up keycap laser engraving fixture fixing device.
[0004] To achieve the above objectives, this utility model discloses a flip-up keycap laser engraving fixture fixing device, including a first connecting seat, a second connecting seat, a turntable, a driving device, a mounting plate, and a fixing component;
[0005] The two ends of the turntable are rotatably connected to the first connecting seat and the second connecting seat, respectively. The driving device is connected to the first connecting seat, and the output end of the driving device is connected to the end of the turntable for driving the turntable to rotate.
[0006] The mounting plate is installed on the turntable and spaced apart from the turntable, and the mounting plate is provided with clearance holes;
[0007] The fixing component includes a rotation drive and a pressing component connected to the rotation drive. The rotation drive is mounted on the turntable, and the pressing component has a pressing part. The rotation drive can rotate the pressing component to the pressing part to press down the keycap laser engraving fixture, and can also rotate the pressing component to the outside of the mounting plate.
[0008] Preferably, the second connecting seat is provided with a limiting member, and the turntable is provided with a follower member that cooperates with the limiting member for limiting.
[0009] Preferably, the follower is L-shaped and includes a connecting part and a protruding part. One end of the connecting part is connected to the turntable, and the protruding part is connected to the other end of the connecting part. The limiting member has a U-shaped cross-section with the opening facing outward, and the protruding part is limited and engaged with the inner sidewall of the limiting member.
[0010] Preferably, the movement trajectory of the protrusion is arc-shaped, and there are three limiting members, two of which are located at the extreme positions of the movement trajectory, and the other is located at the lowest position of the movement trajectory.
[0011] Preferably, when the protrusion is rotated to its lowest position, it is parallel to the inner wall of the limiting member.
[0012] Preferably, the mounting plate is detachably connected to the turntable.
[0013] Preferably, there are multiple fixing components, which are distributed on the long side of the mounting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The two ends of the turntable are rotatably connected to the first and second connecting seats, respectively. The output end of the drive device is connected to the end of the turntable, enabling it to rotate. Thus, when processing the top or side of a keycap, the drive device rotates the turntable to a horizontal or tilted state. The mounting plate installed on this state and the keycap laser engraving fixture fixed to the mounting plate are also in a horizontal or tilted state, allowing laser engraving to be performed on the top or side of the keycap. Through the linkage design of the turntable and the drive device, a single mounting plate has dual horizontal and tilting station functions. This not only reduces the equipment's footprint but also allows keycaps to be processed in one station at a time, improving processing speed and efficiency.
[0019] The mounting plate has clearance holes, which allow the positioning pins on the keycap laser engraving fixture to fit into the clearance holes; the mounting plate and the turntable are spaced apart, which prevents interference between the positioning pins on the keycap laser engraving fixture and the turntable.
[0020] The fixing component can fix the keycap laser engraving fixture to the mounting plate through the pressing part of the pressing component. At the same time, when placing the keycap laser engraving fixture, the pressing component can be rotated to the outside of the mounting plate to avoid the pressing component affecting the placement of the fixture.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] A flip-up keycap laser engraving fixture fixing device, see [link / reference] Figures 1-3 The assembly includes a first connecting seat 100, a second connecting seat 200, a turntable 300, a drive device 400, a mounting plate 500, and a fixing assembly 600. The two ends of the turntable 300 are rotatably connected to the first connecting seat 100 and the second connecting seat 200, respectively. The drive device 400 is connected to the first connecting seat 100, and its output end is connected to the end of the turntable 300, used to drive the turntable 300 to rotate to a horizontal or tilted state. The mounting plate 500 is mounted on the turntable 300 and spaced apart from it. The mounting plate 500 has clearance holes 510. The fixing component 600 includes a rotation drive 610 and a pressing component 620 connected to the rotation drive 610. The rotation drive 610 is mounted on the turntable 300. The pressing component 620 is provided with a pressing part. The rotation drive 610 can rotate the pressing component 620 to the pressing part to press down the keycap laser engraving fixture, and can rotate the pressing component 620 to the outside of the mounting plate 500.
[0032] With the keycap laser engraving fixture in its normal position, the rotating drive 610 rotates the pressing member 620 to the outside of the mounting plate 500, preventing it from interfering with the placement of the keycap laser engraving fixture. During processing, the keycap laser engraving fixture is placed on the mounting plate 500, and the fixture's positioning pin is inserted into the clearance hole 510 for positioning. Then, the rotating drive 610 rotates the pressing member 620 to press down on the keycap laser engraving fixture, thereby fixing the fixture. When processing the top or side surface of the keycap, the drive device 400 drives the turntable 300 to rotate to a horizontal or tilted state. The mounting plate 500 and the keycap laser engraving fixture fixed to the mounting plate 500 are also in a horizontal or tilted state, allowing laser engraving to be performed on the top or side surface of the keycap. The linkage design between the turntable 300 and the drive unit 400 enables a single mounting plate 500 to have both horizontal and tilting dual-station functions. This not only reduces the equipment's footprint but also allows keycaps to be processed in one go at the same station, improving processing speed and efficiency. The mounting plates 500 are spaced apart from the turntable 300, which prevents interference between the positioning posts on the keycap laser engraving fixture and the turntable 300.
[0033] The mounting plate 500 has multiple fixing components 600 distributed along its long side. These multiple fixing components 600 improve the fixation effect of the keycap laser engraving fixture. Distributing the fixing components 600 along the long side of the mounting plate 500 reduces the length of the turntable 300, alleviating the problem of insufficient rigidity caused by its length, and also preventing interference between the pressing component 620 and the connecting parts during rotation.
[0034] Furthermore, the turntable 300 is provided with multiple mounting positions 311, and the rotation drive 610 is mounted in any of these mounting positions 311. Specifically, the turntable 300 has a row of connecting holes, preferably threaded holes, located on the outer side of the long side of the mounting plate 500, which serve as mounting positions 311. By providing multiple mounting positions to fix the rotation drive 610, the mounting position 311 of the rotation drive 610 can be adjusted according to different keycap laser engraving fixtures, thereby adjusting the pressing position of the pressing member 620 and preventing the pressing member 620 from pressing down on the keycap and damaging it.
[0035] In one embodiment, the second connecting seat 200 is provided with a limiting member 210, and the turntable 300 is provided with a follower member 320 that cooperates with the limiting member 210. Through the limiting cooperation between the limiting member 210 and the follower member 320, the rotation accuracy of the turntable 300 is ensured, and the posture deviation caused by the cumulative error of the drive device 400 is avoided, thereby improving the laser engraving accuracy and processing effect.
[0036] Specifically, the follower 320 is L-shaped, including a connecting portion 321 and a protrusion 322. One end of the connecting portion 321 is connected to the turntable 300, and the protrusion 322 is connected to the other end of the connecting portion 321. The limiting member 210 has a U-shaped cross-section with its opening facing outwards, and the protrusion 322 is in a limiting fit with the inner wall of the limiting member 210. When the turntable 300 is rotating normally, the protrusion 322 of the follower 320 does not contact the limiting member 210 as it rotates. When its rotational posture deviates, the protrusion 322 of the follower 320 is in a limiting fit with the inner wall of the limiting member 210, which restricts the rotation of the turntable 300. This allows the operator to perform timely maintenance when they see abnormal rotation of the turntable 300.
[0037] Furthermore, the movement trajectory of the protrusion 322 is arc-shaped. There are three limiting members 210, two of which are located at the extreme positions of the movement trajectory. When the turntable 300 rotates beyond the extreme position, the inner wall of the limiting member 210 restricts the protrusion 322 to limit the rotation of the turntable 300, preventing abnormalities in the turntable 300 and damage to the keycap laser engraving fixture due to inertial overshoot during rotation. The other limiting member 210 is located at the lowest position of the movement trajectory. When the turntable 300 is in a horizontal state, the protrusion 322 rotates to the lowest position, and the protrusion 322 is parallel to the inner wall of the limiting member 210. The positional relationship between the protrusion 322 and the inner wall of the limiting member 210 can help adjust the posture of the turntable 300.
[0038] In another embodiment, the mounting plate 500 is detachably connected to the turntable 300. The mounting plate 500 is used to support the keycap laser engraving fixture. The positioning pins on different keycap laser engraving fixtures are distributed differently. By detachably connecting the mounting plate 500 to the turntable 300, when other types of mounting plates 500 are needed to support other types of keycap laser engraving fixtures, other mounting plates 500 can be replaced, so that the device can fix different types of keycap laser engraving fixtures, and has high versatility.
[0039] In another embodiment, the turntable 300 includes a rotating plate 310, two connecting plates 330 located outside the long side of the rotating plate 310, and at least one support block 340 located on the rotating plate 310. The connecting plate 330 includes a support bar 331 connected to the rotating plate 310 and a connecting bar 332 connected to the outside of the connecting bar 332. The top surfaces of the connecting bar 332 and the support block 340 are coplanar. The mounting plate 500 is connected to the support bar 331 and the support block 340, and the fixing assembly 600 is connected to the connecting bar 332.
[0040] In this embodiment, the rotation drive 610 includes a motor 611 and a connector 612. One end of the connector 612 is connected to the output shaft of the motor 611, and the other end of the connector 612 is provided with a threaded hole. The pressing member 620 is a bolt that is threaded into the threaded hole.
[0041] The connector 612 has multiple threaded holes, so the pressing component 620 can adjust its connection position according to the keycap laser engraving fixture of different sizes, thereby fixing the keycap laser engraving fixture of different sizes, which has high versatility.
