Description

Technical Field

[0001] This utility model relates to the field of keyboard hole CNC engraving machine technology, and in particular to a fully automatic keyboard hole CNC engraving machine with loading and unloading. Background Technology

[0002] In the current booming wave of digital office and e-sports entertainment industries, keyboards, as core input devices, are experiencing explosive growth in market demand. Simultaneously, consumers' demands for keyboard quality, performance, and personalized customization are increasing daily. From the popularity of mechanical keyboards to the growing appeal of customized keyboards with unique designs and special function layouts, this undoubtedly poses more stringent challenges to keyboard manufacturing processes. To address these challenges, developing a new type of CNC engraving machine for keyboard holes, featuring fully automated loading and unloading capabilities and effectively overcoming the shortcomings of traditional equipment, has become a crucial issue urgently needing to be resolved within the industry. This would not only significantly improve keyboard production efficiency and processing quality, and reduce production costs, but also greatly enhance the competitiveness of enterprises in the market, meet ever-changing market demands, and drive the keyboard manufacturing industry towards intelligence and efficiency.

[0003] Currently, CNC engraving machines for keyboard holes on the market mainly consist of high-precision machining units and control systems. The processing quality and efficiency of keyboard holes are key factors determining the overall quality and production efficiency of the keyboard. Traditional keyboard hole processing techniques, such as manual drilling and semi-automatic engraving, are no longer sufficient to meet the current demands for large-scale, high-precision, and diversified production. Manual drilling heavily relies on the operator's experience and skill level, resulting in extremely low processing efficiency, with each keyboard hole often taking several minutes to process. Furthermore, it produces significant precision errors and large diameter deviations, greatly affecting the keyboard's assembly accuracy and user experience, leading to a high defect rate. While semi-automatic engraving improves processing precision to some extent, it still requires substantial manual intervention in the loading and unloading processes, increasing labor intensity and costs. Moreover, frequent manual operation is prone to introducing errors, making it difficult to achieve continuous and efficient automated production. With its superior automation and high-precision machining capabilities, CNC engraving machines have gradually emerged in the field of keyboard hole processing and become the mainstream processing equipment in the industry. Through pre-written CNC programs, CNC engraving machines can accurately control the movement trajectory and cutting parameters of the tool to achieve precise machining of keyboard holes. However, when traditional CNC engraving machines are applied to keyboard hole processing, they still expose many problems. In the loading and unloading process, the degree of automation is low, and simple semi-automatic loading devices with manual loading are often used. This not only consumes a lot of manpower and time, resulting in low production efficiency, but also makes it difficult to guarantee the positioning accuracy of loading and unloading due to the uncertainty of manual operation, which further affects the machining accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fully automatic keyboard hole CNC engraving machine for loading and unloading, aiming to improve the problem of low automation in the loading and unloading process of traditional keyboard hole CNC engraving machines in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic keyboard hole CNC engraving machine with loading and unloading, comprising a base plate, wherein a loading mechanism is fixedly connected to the top of the base plate, the loading mechanism is used to load and unload keyboards, and a positioning mechanism is provided on the top of the loading mechanism, wherein the positioning mechanism is used to position and clamp keyboards of different sizes.

[0009] As a further description of the above technical solution: The limiting component includes a limiting plate one, which is fixed to the center of the bottom surface of the conveyor table. The outer wall of the connecting shaft three is rotatably connected to a sliding plate, and sliding grooves are provided on adjacent sides of the outer walls of the two sliding plates.

[0010] As a further description of the above technical solution: The elastic component includes a sliding shaft, the bottom of which is slidably connected to the inner wall of the sliding box, and a tapered column is fixedly connected to the outer wall of the sliding shaft near the top.

A sliding shaft slides on the inner wall of the sliding box, and a conical column is fixed on the outer wall of the sliding shaft. The connecting shaft two fixed at the bottom of the outer wall of the sliding shaft can make the conical column contact the positioning plate under the elastic action of the spring two. The other end of the positioning plate can contact and squeeze the keyboard to be engraved, thereby realizing the positioning function and preventing the keyboard from shaking violently during engraving.
