[0029] To achieve the purpose of scanning and testing the keyboard under test, this device adopts the following technical solution: A display screen 2 is fixedly installed on one side of the testing machine body 1; an industrial control computer 3 is fixedly installed inside the testing machine body 1; a linear drive module 4 is installed on the top of the testing machine body 1; a contour scanner 5 is externally connected to the linear drive module 4; a start / stop controller 6 with an emergency stop button is fixedly installed on one side of the testing machine body 1; the industrial control computer 3 and the linear drive module 4 are connected by electrical signals; the industrial control computer 3 sends control commands to the linear drive module 4 according to a preset program, driving the linear drive module 4 to move according to the set speed and trajectory; the linear drive module 4 and the contour scanner 5 are mechanically connected; during the movement, the linear drive module 4 directly drives the contour scanner 5 to move synchronously, ensuring… The contour scanner 5 can scan different positions on the keyboard. The contour scanner 5 is connected to the industrial computer 3 via a data transmission cable. The contour scanner 5 transmits the scanned keyboard contour information to the industrial computer 3 in real time, where the industrial computer 3 processes the information. The start / stop controller 6 with an emergency stop button is connected to the industrial computer 3 via an electrical signal. When the operator presses the start button, the start / stop controller 6 sends a start signal to the industrial computer 3, which then starts the relevant program. When the emergency stop button is pressed, a stop signal is sent, and the industrial computer 3 controls all operating components to stop working. The industrial computer 3 is connected to the display screen 2 via a data transmission cable. The industrial computer 3 transmits the processed scan results and information on faulty keys to the display screen 2, enabling the display screen 2 to display the relevant content in real time.

[0030] To achieve rapid assembly / disassembly and precise positioning of the material placement module component 8 and the support platform component 7, the device employs the following technical solution: The keyboard support module 81 is located inside the module positioning frame 72 and slidably connected to it; a cavity 83 and a through groove 85 are formed on one side wall of the cavity 83; the through groove 85 is located above the slide groove 84; the release button 861 passes through the through groove 85 and is slidably connected to it; a connecting plate 862 is located inside the cavity 83 and slidably connected to it; a magnetic block 863 passes through the slide groove 84 and is slidably connected to it; one end of the magnetic block 863 extends into the magnetic groove 73 and is magnetically connected to it; one end of the spring piece 864 is fixedly connected to one side wall of the connecting plate 862; the other end of the connecting plate 862 is fixedly connected to one side wall of the cavity 83; and both ends of the spring 865 are fixedly connected to the two side walls of the spring piece 864, respectively. When the release button 861 is pressed, it slides along the through groove 85 and drives the magnetic block 863 to retract along the slide groove 84 via the connecting plate 862, while compressing the spring 864 and the spring 865. After being released, the spring 864 and the spring 865 return to their original positions, pushing the magnetic block 863 into the magnetic groove 73 to complete the fixation. The sliding connection ensures smooth movement of each component, and the magnetic attraction enables quick positioning and locking. By using a replaceable material placement module assembly 8, quick adaptation to different keyboard models can be achieved. For places connected to or passing through the magnetic block 863, such as the inner wall of the slide groove 84 and the connecting plate 862, non-metallic materials are used to prevent the magnetic block 863 from being magnetically interfered with by the metal material when it moves. This ensures that the magnetic block 863 can smoothly enter or exit the magnetic groove 73, guaranteeing the quick replacement and stable connection of the material placement module assembly 8, and ultimately achieving efficient and accurate keyboard quality testing.

[0031] The usage process of this utility model is as follows: When using this utility model, firstly, preliminary preparations are made. The operator selects the corresponding material placement module component 8 according to the model of the keyboard to be tested, presses the release button 861 on the material placement module component 8 and slides it into the through groove 85, so that the magnetic block 863 is put into the slide groove 84. Then, it is aligned with the module positioning frame 72 in the support platform component 7 and slowly placed in. After releasing the release button 861, under the elastic force of the spring 864 and the spring 865, the magnetic blocks 863 on both sides of the keyboard support module 81 will slide out along the slide groove 84 and extend into the module positioning frame 7. Within the magnetic suction slot 73 of component 2, a stable connection is achieved between the material placement module assembly 8 and the support platform assembly 7 through magnetic attraction. Then, based on the drawing parameters of this keyboard model, the corresponding scanning program is set in the industrial control computer 3 to complete the preliminary preparation. During operation, the operator smoothly places the keyboard material into the mold cavity 82 at the top of the keyboard support mold 81, ensuring the keyboard is properly positioned. Next, the pre-set program is opened, and the start button on the start / stop controller 6 with an emergency stop button is pressed simultaneously with both hands. The program begins to run. At this time, the linear drive module 4 starts under the control of the industrial control computer 3, driving the contour scanner 5 to move along the preset trajectory. Simultaneously, the contour scanner 5 scans the outline of the keyboard's keycaps. During the scanning process, the contour scanner 5 transmits the collected contour information to the industrial control computer 3 in real time. After processing and analyzing the information, the industrial control computer 3 displays the scanning results on the display screen 2, highlighting defective keys with enhanced display. The industrial control computer 3 also records the defect information. After testing, the operator can directly remove the tested keyboard from the mold cavity 82 and place the next keyboard to be tested into the mold cavity 82, repeating the above operation to continue testing. When it is necessary to change to test different keyboard models, the operator only needs to... Press the release button 861 on the material placement module assembly 8 and slide it into the through groove 85. At the same time as the release is performed, the finger is in the through groove 85. At this time, the release button 861 drives the magnetic block 863 to compress the spring 864 and the spring 865 through the connecting plate 862, so that the magnetic block 863 exits from the magnetic groove 73 and retracts into the slide groove 84. In this state, the material placement module assembly 8 can be directly removed from the module positioning frame 72. The release and removal action is all that is needed. Then, following the steps prepared in advance, replace the material placement module assembly 8 with the corresponding model and set the program to quickly switch to the new detection model.

[0032] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
