Description

Technical Field

[0001] This utility model belongs to the field of testing technology, and specifically relates to a keyboard adhesive film size testing device. Background Technology

[0002] Keyboard protective films, also known as keyboard covers, are thin film materials used to protect computer keyboards. Primarily made of soft plastic, they completely cover the keyboard surface to prevent damage or corrosion from dust, liquids, or other contaminants. Their dimensional accuracy directly determines the fit to the keyboard and is one of the core indicators affecting the protective effect. Therefore, during the production process, random checks of the keyboard protective film's shape and the position and size of the key openings are necessary to ensure that the product accurately matches the corresponding keyboard model.

[0003] Currently, the inspection of keyboard adhesive films relies mainly on two methods: manual measurement and automated equipment measurement. Manual measurement is not only inefficient and labor-intensive, but also prone to inaccurate results due to human error, making it difficult to meet production needs. While automated equipment measurement overcomes the shortcomings of manual measurement, automated measuring equipment generally suffers from complex structures, high costs, long processing times, and difficult debugging. Therefore, it is necessary to design a keyboard adhesive film size detection device to effectively solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] See Figure 1-2 As shown, a keyboard adhesive film size detection device includes an operating table 1, which is spliced ​​from aluminum profiles. A barrier 8 is provided on the table surface of the operating table 1, and casters 7 are provided at the lower end of the operating table 1 to facilitate its movement. In this embodiment, the casters 7 are made of casters, which realizes the integration of movement and fixation, and precise horizontal adjustment to ensure the stability of the operating table 1.

[0024] The operating platform 1 is equipped with a moving module 2, an analysis and processing module 3, and a testing platform 4 for placing the keyboard adhesive film to be tested. The testing platform 4 is located between the moving module 2 and the analysis and processing module 3. A camera 5 is mounted on the moving module 2 to capture images of the keyboard adhesive film placed on the testing platform 4. The camera 5 is connected to the analysis and processing module 3, which receives and analyzes the images captured by the camera 5. The system also includes a control system 6, which controls the testing device. The testing platform 4 has three sets of testing positions.

[0025] Furthermore, in this embodiment, the mobile module 2 includes a support base 21 and an XYZ three-axis slide mechanism 22 disposed on the support base 21; during installation, the XYZ three-axis slide mechanism 22 is disposed on the operating table 1 via the support base 21.

[0026] Furthermore, in this embodiment, the testing platform 4 includes a base 41 fixed on the table surface of the operating platform 1, and the cross-section of the base 41 is U-shaped; a fixture plate 42 for placing keyboard adhesive film is provided at the upper end of the groove wall of the base 41, and the fixture plate 42 is provided with three sets of testing positions for placing keyboard adhesive film, but not limited to three sets, and can be set to other numbers as long as the requirements are met; in this embodiment, in order to improve the installation accuracy of the fixture plate 42 and prevent the fixture plate 42 from slipping off the base 41, a positioning pin 411 is provided at the upper end of the base 41, and a positioning hole 421 adapted to the positioning pin 411 is provided on the lower end surface of the fixture plate 42.

[0027] Furthermore, in this embodiment, the camera 5 is an industrial camera, which is mounted on the XYZ three-axis slide mechanism 22 via a bracket. The XYZ three-axis slide mechanism 22 can drive the camera 5 to move in the X, Y, and Z directions, thereby enabling image acquisition of the keyboard film at different detection positions.

[0028] Furthermore, in this embodiment, the analysis and processing module 3 includes an image processing control module 31 and a human-computer interaction interface 32. During operation, after receiving the image captured by the camera 5, the image processing control module 31 performs preprocessing and feature extraction to calculate the actual size data of the keyboard membrane and automatically compares it with a preset standard threshold. If a parameter exceeds the threshold (such as the external dimensions of the keyboard membrane or the position dimensions of the key openings), it is marked as unqualified, and the specific deviation value is recorded. The human-computer interaction interface 32 displays the original image of the membrane captured by the camera 5 and the optimized image preprocessed by the image processing control module 31, and overlays the size measurement data and the qualified / unqualified judgment results, which is convenient for operators to view. At the same time, the standard size threshold of different models of keyboard membranes can be entered into the image processing control module 31 through the human-computer interaction interface 32.

[0029] Furthermore, the control system 6 includes a control cabinet 61 and a teach pendant 62; wherein, in this embodiment, the control cabinet 61 is a PLC control cabinet; during operation, the teach pendant 62 allows operators to quickly and easily correct the image acquisition points of the camera 5, and switch between manual and automatic working modes of the camera 5, and select single-station, multi-station, or full-station automatic operation in automatic mode.

[0030] The working principle of this utility model is as follows:

[0031] During operation, firstly, select the corresponding fixture plate 42 according to the keyboard membrane model, and install the fixture plate 42 onto the base 41. Then, place the keyboard membrane to be tested onto the detection position. Select the standard size threshold of the corresponding keyboard membrane model through the human-machine interface 32. Then, select the manual or automatic working mode through the teach pendant 62 and start the detection program. At this time, the camera 5, driven by the XYZ three-axis slide mechanism 22, acquires images of the keyboard membrane in the detection position. After the acquisition is completed, the camera 5, driven by the XYZ three-axis slide mechanism 22, resets to the standby position.

[0032] It should be noted that when the manual working mode is selected, the operator controls the XYZ three-axis slide mechanism 22 through the teach pendant 62 to drive the camera 5 to acquire images of the keyboard membrane in the corresponding detection position; while when the automatic working mode is selected, the camera 5 acquires images of the keyboard membrane in the corresponding detection position under the automatic drive of the XYZ three-axis slide mechanism 22.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
