Description

Technical Field

[0001] This utility model relates to the field of silicone strip pressing technology, and in particular to a pneumatic pressing device for a built-in silicone strip for a tablet computer keyboard. Background Technology

[0002] The built-in silicone strip used in tablet keyboards needs to be pressed together. By pressing the silicone strip, it can be tightly attached between the keyboard's circuit board and membrane during subsequent assembly, forming a stable structure. This tight fit helps prevent the silicone strip from loosening or falling off during use, thus ensuring the keyboard's stability and durability. At the same time, it also prevents deformation. Before pressing, the silicone strip may have certain shape deviations or deformations. Pressing makes its shape more regular and better matches with other parts of the keyboard, thereby improving the overall structural stability.

[0003] Patent application number 202122251771.6 discloses a pneumatic pressing device for a built-in silicone strip for a tablet keyboard, including a support mechanism, a top support plate on the upper part of the support mechanism, a silicone strip placement mechanism on the support plate, a silicone strip pressing mechanism on one side of the silicone strip placement mechanism, and a lifting control component on one side of the silicone strip placement mechanism, with a pressing component at the output end of the lifting control component.

[0004] However, while traditional pneumatic pressing devices with built-in silicone strips for tablet keyboards improve the stability of manual pressing, the mechanical pressing process is cumbersome and the pressing efficiency is relatively low. Therefore, there is an urgent need for a pneumatic pressing device with built-in silicone strips for tablet keyboards to solve the above problems.

[0005] For example, most traditional devices are semi-automatic. The automatic pressing process still requires manual assistance in feeding the silicone strips. After feeding, the silicone strips need to be transported to the pressing device for pressing. The feeding process, the conveying process, and the feeding process all take up a lot of time, affecting efficiency. Utility Model Content

[0006] This utility model discloses a pneumatic pressing device for a built-in silicone strip for a tablet keyboard, which aims to solve the technical problem that, although the pneumatic pressing device for a built-in silicone strip for a tablet keyboard improves the stability of manual pressing, the mechanical device's conveying and pressing process is cumbersome and the pressing efficiency is relatively low.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pneumatic pressing device for a built-in silicone strip for a tablet keyboard includes a worktable and further includes: a feeding mechanism: the feeding mechanism is set on a turntable at the top of the worktable, with connecting plates on both outer walls of the turntable, and a support platform on one outer wall of each of the two connecting plates; a support pad on one side of the worktable, and a side bracket on one side of the support pad; a cylinder is mounted on the top of the side bracket, and a pressing pad is mounted on the piston end of the cylinder, with the pressing pad located directly above the support pad; and a protective mechanism: the protective mechanism is set on the two support platforms.

[0009] In this solution, two support platforms are used in conjunction with a turntable. During the rotation of the turntable, the two support platforms can be alternately driven to enter the underside of the pressing pad for pressing. Meanwhile, the other support platform, which is opposite to the support platform under the pressing pad, can be loaded simultaneously. As the current pressing process ends, the other support platform, which has finished loading, can rotate with the silicone strip to the underside of the pressing pad. The dual-station alternating operation effectively improves the pressing efficiency.

[0010] In a preferred embodiment, the protective mechanism includes a limiting notch provided on the outer wall of the support platform, a movable frame sleeved on the outer wall of the limiting notch, a sliding rod provided at each of the four corners of the bottom outer wall of the movable frame, the bottom end of the sliding rod slidably inserted into the outer wall of the support platform, a return spring sleeved on the outer wall of the sliding rod, and a cover provided at the edge of the bottom outer wall of the pressing pad, the cover cooperating with the movable frame.

[0011] With the reset spring and movable frame in place, the movable frame is supported by the reset spring to a height higher than the upper surface of the support platform in the initial state. This forms a protective barrier around the top of the support platform, preventing the silicone strip material from falling from the top of the support platform during the dual-station rotating feeding process. Furthermore, with the cooperation of the sleeve and movable frame, the movable frame will not affect the material when the pressing pad is pressed down.

[0012] As described above, a pneumatic pressing device for a built-in silicone strip in a tablet keyboard includes a worktable and further includes: a feeding mechanism: the feeding mechanism is mounted on a turntable at the top of the worktable, with connecting plates on both outer walls of the turntable, and a support platform on one outer wall of each of the two connecting plates; a support pad on one side of the worktable, and a side bracket on one side of the support pad; a cylinder is mounted on the top of the side bracket, and a pressing pad is mounted on the piston end of the cylinder, with the pressing pad located directly above the support pad; and a protective mechanism: the protective mechanism is mounted on the two support platforms. The pneumatic pressing device for a built-in silicone strip in a tablet keyboard provided by this utility model has the technical effect of improving the feeding stability and pressing efficiency of the silicone strip.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] The pneumatic pressing device for a built-in silicone strip in a tablet keyboard disclosed in this utility model is mainly used in scenarios where, although the pneumatic pressing device for a built-in silicone strip in a traditional tablet keyboard improves the stability of manual pressing, the mechanical device's conveying and pressing process is cumbersome and the pressing efficiency is relatively low.

[0020] Reference Figure 1 , Figure 2 and Figure 3A pneumatic pressing device for a built-in silicone strip for a tablet keyboard includes a workbench 1 and a feeding mechanism: the feeding mechanism is set on a turntable 2 at the top of the workbench 1, and connecting plates are provided on both outer walls of the turntable 2. A bearing platform 7 is provided on one outer wall of each of the two connecting plates. A support pad 15 is provided on one side of the workbench 1, and a side bracket 3 is provided on one side of the support pad 15. A cylinder 4 is installed on the top of the side bracket 3, and a pressing pad 5 is installed on the piston end of the cylinder 4. The pressing pad 5 is located directly above the support pad 15.

[0021] Protective mechanism: The protective mechanism is set on the two support platforms 7.

[0022] Specifically, by using two carrier platforms 7 together with the turntable 2, the two carrier platforms 7 can be alternately driven into the underside of the pressing pad 5 for pressing during the rotation of the turntable 2. Meanwhile, the other carrier platform 7, which is opposite to the carrier platform 7 under the pressing pad 5, can be loaded simultaneously. As the current pressing process ends, the other carrier platform 7, which has finished loading, can rotate with the silicone strip to the underside of the pressing pad 5. The dual-station alternating operation effectively improves the pressing efficiency.

[0023] The top of the support pad 15 and the bottom of the support platform 7 are on the same plane. The support pad 15 with appropriate height can provide stable support during the pressing process.

[0024] The pressing pad 5 has connecting frames 6 on both outer walls, and sensor components are provided on the bottom outer wall of the connecting frames 6. The sensor components can capture the position of the material feeding platform 7 in a timely manner, ensuring that the material feeding platform 7 can accurately correspond to the pressing pad 5. The quality of the silicone strip after the pressing pad 5 presses the platform 7 is higher.

[0025] Reference Figure 1 and Figure 2 In a preferred embodiment, a motor 8 is provided on the bottom outer wall of the workbench 1, and one end of the output shaft of the motor 8 is connected to the bottom outer wall of the turntable 2.

[0026] Reference Figure 3 In a preferred embodiment, the protective mechanism includes a limiting notch 11 provided on the outer wall of the support platform 7. A movable frame 10 is sleeved on the outer wall of the limiting notch 11. Slide rods 12 are provided at the four corners of the bottom outer wall of the movable frame 10. The bottom end of the slide rod 12 is slidably inserted into the outer wall of the support platform 7. A return spring 14 is sleeved on the outer wall of the slide rod 12. A cover 9 is provided at the edge of the bottom outer wall of the pressing pad 5. The cover 9 is used in conjunction with the movable frame 10.

[0027] Specifically, through the reset spring 14 and the movable frame 10, in the initial state, the movable frame 10 is supported by the reset spring 14 to a height higher than the upper plane of the support platform 7, thus forming a protective barrier around the top of the support platform 7 to prevent the silicone strip material from falling from the top of the support platform 7 during the dual-station rotating feeding process. Furthermore, with the cooperation of the sleeve 9 and the movable frame 10, the movable frame 10 will not affect the pressing pad 5 when it is pressed down.

[0028] Reference Figure 4 In a preferred embodiment, the top outer wall of the support pad 15 is provided with a plurality of adapter grooves 13.

[0029] It should be noted that since the bottom end of the slide bar 12 passes through the support platform 7, the adapter groove 13 can play an adaptation and guiding role in the dual-station loading process, avoiding conflict between the support pad 15 used for support and the movement of the bottom end of the slide bar 12, thus ensuring the stability of the dual-station loading process.

[0030] Working principle: During use, the silicone strip material is manually loaded onto the support platform 7. Then, driven by the motor 8, the turntable 2 will move the loaded support platform 7 to press the pressing pad 5 directly below it. At the same time, the other support platform 7, which is opposite to the support platform 7 below the pressing pad 5, can be loaded simultaneously. This process is repeated. During this process, the movable frame 10 is supported by the return spring 14 to a height higher than the upper plane of the support platform 7. This forms a protective barrier around the top of the support platform 7, preventing the silicone strip material from falling from the top of the support platform 7 during the dual-station rotation loading process.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
