Example 2

[0021] Based on Embodiment 1, this utility model is as follows: Figure 1-3 As shown, the bottom of the connecting plate 9 has a slot 18, and the right side of the inner cavity of the slot 18 has a mounting groove 21. The top of the industrial camera 17 is fixedly connected to a plug 19, which is movably connected to the inner cavity of the slot 18. The right side of the plug 19 has a socket 20. The right side of the inner cavity of the mounting groove 21 is fixedly connected to a second electric telescopic rod 22. The left end of the second electric telescopic rod 22 is movably connected to the inner cavity of the socket 20. The left end of the top of the base plate 1 is fixedly connected to a battery box 4, and the inner cavity of the battery box 4 is fixedly connected to a battery. The right end of the top of the base plate 1 is fixedly connected to an industrial camera 17. Toolbox 2 has a partition fixedly connected to its inner cavity. Alarm 10 is fixedly connected to the front right side of the top of workbench 3. The top and bottom of cleaning sponge 16 are on the same horizontal plane. PLC controller 11 is fixedly connected to the front of workbench 3. The input terminal of PLC controller 11 is electrically connected to the output terminal of industrial camera 17. The output terminal of PLC controller 11 is electrically connected to the input terminals of first electric slide 6, alarm 10, second electric slide 12, first electric telescopic rod 13, third electric slide 14 and second electric telescopic rod 22.

[0022] The slot 18 of the connecting plate 9 in this technical solution cooperates with the insertion block 19 of the industrial camera 17. The second electric telescopic rod 22 is inserted into the insertion hole 20 for fixation. Disassembly only requires controlling the telescopic rod to retract, without the need for tools, which facilitates quick replacement or maintenance of the industrial camera 17 and improves the ease of equipment maintenance. The battery box 4 of the base plate 1 has a built-in battery, which can power the device in the event of a power outage or in a mobile testing scenario, ensuring that the testing work is not interrupted and enhancing the environmental adaptability and emergency response capability of the equipment. The toolbox 2 on the right side of the workbench 3 stores testing tools and spare parts in a classified manner through partitions, which is convenient for operators to quickly access, reduces equipment fault diagnosis and maintenance time, and ensures production continuity. The alarm 10 of the workbench 3 can issue a timely warning when defective products are detected, which is convenient for operators to handle quickly. The top and bottom of the cleaning sponge 16 are kept at the same level to ensure uniform contact with the button surface during cleaning, improve the cleaning effect, and avoid affecting the detection accuracy due to uneven cleaning.

[0023] The working principle of this utility model is as follows: When in use, the keyboard is placed on the placement platform 5, and the PLC controller 11 starts the third electric slide 14, which drives the movable plate 15 and the cleaning sponge 16 to move and wipe the lens of the industrial camera 17 to remove dust. After cleaning, the first electric slide 6 adjusts the front and rear positions of the support column 7 and the top plate 8, the second electric slide 12 adjusts the left and right positions of the industrial camera 17, and the first electric telescopic rod 13 controls the height of the industrial camera 17 so that it is aligned with the key to capture an image. The industrial camera 17 transmits the image data to the PLC controller 11. The controller analyzes the image, and if a defect is detected in the key, it immediately activates the alarm 10 to issue a warning. If the industrial camera 17 needs to be replaced, the PLC controller 11 controls the second electric telescopic rod 22 to retract, so that it is disengaged from the socket 20, and the plug 19 can be removed from the slot 18. The battery box 4 provides power to the device when the power is off, and the toolbox 2 is used to store maintenance tools.
