Technical Field
[0001] This invention relates to the field of automated keyboard testing technology, specifically to an intelligent testing device for the installation accuracy of keyboard keycaps based on AI vision. Background Technology
[0002] The quality of keyboard keycap installation is a core indicator that determines the keyboard's feel, stability, and lifespan. In automated keyboard assembly lines, high-precision online testing is required for keycap installation height, key travel, tilt, looseness, jamming, misalignment, and missing keycaps. The current industry-standard testing methods have the following significant drawbacks: Low efficiency and poor consistency of manual testing: relying on visual observation and manual pressing, it's impossible to quantify height and travel, leading to missed or false detections, and it's unsuitable for high-speed production lines; Limited testing functions: only height or pressing force can be measured, unable to simultaneously perform integrated testing of height, travel, tilt, and misalignment; Lack of pre-processing for cleaning impurities: dust and lint in keycap crevices can cause laser misjudgments, reducing testing accuracy; Lack of automatic marking of defective products: manual location of rework points is slow and prone to omissions, impacting production line efficiency. Therefore, this invention provides an AI vision-based intelligent keycap installation accuracy testing device. Through AI vision, it globally locates the keycap position and, combined with non-contact laser detection, achieves integrated intelligent testing of keycap installation height, pressing travel, and installation misalignment.

[0034] The working principle is as follows: The keyboard is installed on the mounting platform 2, and the clamping part 8 is controlled by the clamping electric cylinder 7 to clamp and fix it. First, the impurities on the keyboard are pre-cleaned. Specifically, the pre-treatment box 4 is flipped by the flipping motor 9, so that the pre-treatment box 4 is flipped and positioned above the keyboard. The second motor 11 drives the second lead screw 12 to rotate, so that the second slide 14 moves. The third motor 15 drives the third lead screw 16 to rotate, so that the third slide 17 moves. The adsorption control electric cylinder 1701 controls the adsorption part 18 to move toward the keyboard, and the adsorption collection box 10 works to adsorb and collect impurities in various areas of the keyboard, thus completing the pre-treatment of the keyboard.
[0035] Furthermore, the installation height of each key on the keyboard is detected. Angle motor 20 drives angle disk 21 to rotate, positioning the distance detection element above the keyboard. Motor 5 drives lead screw 6 to rotate, moving slide 19. The AI visual recognition device guides laser detector 29 to precisely move to the center position directly above each keycap, emitting a laser that strikes each key to achieve distance detection. The detected distance is the installation height of the key when it is not pressed. Specifically, the system preset distance for the laser to strike the non-key area on the platform or keyboard is L, and the distance for the laser to strike the key is D, thus the installation height of the key is LD. For adjusting the detection position, motor 24 drives control gear 25 to rotate, causing linkage gear 26 to rotate. Electromagnetic sliding rod 27 moves radially and clamps the end of angle lead screw 23, achieving linkage between angle lead screw 23 and linkage gear 26. This, in turn, drives detection seat 28 to move, completing the position adjustment for detecting the installation height of keys in different positions.
[0036] Furthermore, the angle of the press travel detection element is adjusted and positioned above the keyboard. At this point, two detection methods are employed: First, position motor 37 drives position screw 38 to rotate, causing position seat 39 to move. Position motor 41 drives position screw 42 to rotate, causing position seat 43 to move. This positions the laser detector 40 above the laser sleeve 44, and the AI vision recognition device guides the laser sleeve 44 to precisely align with the center of the keycap. The laser emitted by the laser detector 40 can pass through the inside of the laser sleeve 44 and strike the key. Specifically, the height of the mounting bracket 36 is controlled by the detection control cylinder 35, causing the laser sleeve 44 to press each key on the keyboard. After pressing, the laser detector 40... First, a laser beam is emitted and hits the pressed key. The distance is measured as A, and the installation height of the key after pressing is LA. Second, the laser detector 40 and the laser sleeve 44 are misaligned. The AI vision recognition device guides the adjustment of the positions of the laser sleeve 44 and the laser detector 40 so that the laser beam hits the key on the outside of the laser sleeve 44 to detect the tilt state of the key after pressing. For example, on the space bar on the keyboard, one end of the space bar is pressed through the laser sleeve 44, and the laser beam of the laser sleeve 44 hits the non-pressed area of the space bar. The laser beam is controlled to move on the space bar to detect its height. If the height signal output is inconsistent, it is determined that the space bar has an installation abnormality and tilts when the key is pressed.
[0037] For keys that are not installed correctly, the AI vision recognition device outputs the coordinates of all faulty keycaps to the control system, which can then mark them. Specifically, the control marker is located above the keyboard. Based on the detection information, the marking control cylinder 32 controls the marking unit 33 to move above the faulty key. The paint tank 31 transmits marking fuel, which is released through the marking unit 33 to mark the faulty key, making it easier for subsequent operators to return it to the factory for repair.
[0038] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
